Only took it off recently so about 800 miles. Seems fine so far, and the throttle and gear change are noticeably more responsive.

Did agonise over it for ages because a lot of people were saying the turbo couldn't handle it but in the end I checked with Garrett and, although they said it could shorten the life of the turbo, they confirmed that it should be just as strong as the T34, T4etc and they seem to handle much more boost with no problems so I thought what the hell!!

It is more a chirrup than the compressor stall you get with a cossie but I really like the sound, tons better than the dv26 I was using...I'll have to get a recording up sometime
